Self-amplification of radiation from an electron bunch inside a waveguide filled with periodic medium
A. R. Mkrtchyan, L. Sh. Grigoryan, A. A. Saharian +3
We investigate the radiation from a bunch of relativistic electrons moving along the cylindrical waveguide axis, assuming that the waveguide is partially loaded by a medium with pe…
Fermionic condensate and the Casimir effect in cosmic string spacetime
A. Kh. Grigoryan, A. R. Mkrtchyan, A. A. Saharian
We investigate combined effects of nontrivial topology, induced by a cosmic string, and boundaries on the fermionic condensate and the vacuum expectation value (VEV) of the energy-…
Synchrotron and Smith-Purcell radiations from a charge rotating around a cylindrical grating
A. A. Saharian, A. S. Kotanjyan, A. R. Mkrtchyan +1
We investigate the radiation from a charge rotating around conductors with cylindrical symmetry. First the problem is considered with a charge rotating around a conducting cylinder…
Self-amplified Cherenkov radiation from a relativistic electron in a waveguide partially filled with a laminated material
L. Sh. Grigoryan, A. R. Mkrtchyan, H. F. Khachatryan +2
The radiation from a relativistic electron uniformly moving along the axis of cylindrical waveguide filled with laminated material of finite length is investigated. Expressions for…
Optical transition radiation in presence of acoustic waves for an oblique incidence
A. R. Mkrtchyan, V. V. Parazian, A. A. Saharian
Forward transition radiation is considered in an ultrasonic superlattice excited in a finite thickness plate under oblique incidence of relativistic electrons. We investigate the i…
Microwave Cherenkov Radiation from a Particle-in-flight to a Semi-infinite Layered Medium
L. Sh. Grigoryan, A. R. Mkrtchyan, H. F. Khachatryan +2
Some part of the microwave Cherenkov radiation from a particle-in-flight from vacuum to semi-infinite layered medium is redirected by the periodical structure of medium in the back…
